A Neural Network-Based Analysis of the Seasonal Variability of Surface Total Alkalinity on the East China Sea Shelf
(Journal article; Peer reviewed, 2020)Total alkalinity (AT) is an important variable in the regulation of the seawater carbonate chemistry system, determining the capacity to buffer changes in pH. In the coastal oceans, carbonate system dynamics are controlled ... -
Neuroendocrine factors involved in appetite control and feed intake in Atlantic salmon (Salmo salar) reared in Recirculating Aquaculture Systems (RAS).
(Master thesis, 2018-11-15)The control of appetite in vertebrates is a complex process that depends on a range of signals from peripheral tissues and neuro- and endocrine signals originating in the brain. The hypothalamus is believed to be the main ... -
Neurohypophysial and paracrine vasopressinergic signaling regulates aquaporin trafficking to hydrate marine teleost oocytes
(Journal article; Peer reviewed, 2023)The dual aquaporin (Aqp1ab1/Aqp1ab2)-mediated hydration of marine teleost eggs, which occurs during oocyte meiosis resumption (maturation), is considered a key adaptation underpinning their evolutionary success in the ... -
Neuronal cell lipidomics and role of cholesterol in α-synuclein binding and aggregation
(Doctoral thesis, 2019-03-22)α-Synuclein is an intrinsically disordered protein whose fold and multimeric state is strongly affected by its environment. The monomers of α-synuclein are enriched in the presynaptic terminals of dopaminergic ... -
Neutrophils in Atlantic salmon (Salmo salar L.) are MHC class II+ and secret IL-12p40 upon bacterial exposure
(Journal article; Peer reviewed, 2022)Antigen-presentation via major histocompatibility complex (MHC) to T cells is the key event to initiate adaptive immune responses. In teleosts, as in mammals, the main types of professional antigen-presenting cells (APCs) ... -
A new aquareovirus causing high mortality in farmed Atlantic halibut fry in Norway
(Peer reviewed; Journal article, 2015-01)A new aquareovirus was isolated from cultured Atlantic halibut (Hippoglossus hippoglossus) fry at a facility where massive mortalities had occurred during the start-feeding phase. The same virus was also detected in juveniles ... -
New ecosystems in the deep subsurface follow the flow of water driven by geological activity
(Peer reviewed; Journal article, 2019-03-01)Eukarya have been discovered in the deep subsurface at several locations in South Africa, but how organisms reach the subsurface remains unknown. We studied river-subsurface fissure water systems and identified Eukarya ... -
New insights into the early mechanisms of epileptogenesis in a zebrafish model of Dravet syndrome
(Journal article; Peer reviewed, 2020)Abstract Objective: To pinpoint the earliest cellular defects underlying seizure onset (epileptogenic period) during perinatal brain development in a new zebrafish model of Dravet syndrome (DS) and to investigate potential ... -
A new intracellular bacterium, Candidatus Similichlamydia labri sp. nov. (Chlamydiaceae) producing epitheliocysts in ballan wrasse, Labrus bergylta (Pisces, Labridae)
(Peer reviewed; Journal article, 2015-03)Certain wrasse species (Labridae) are used as cleaner fish in salmon farms on the Norwegian coast, reducing salmon louse intensities. The pathogen repertoire of wrasse in Norway is poorly known, and the objective of the ... -
New methods in Palaeopalynology: Classification of pollen through pollen chemistry
(Doctoral thesis, 2021-11-04)Pollen grains are one of the primary tools of palaeoecologists to reconstruct vegetation changes in the past. The description, counting and analysis of pollen grains (palynology) has contributed to our understanding of ... -
A new molecular phylogeny-based taxonomy of parasitic barnacles (Crustacea: Cirripedia: Rhizocephala)
(Peer reviewed; Journal article, 2019)Rhizocephalans are abundant members of marine ecosystems and are important regulators of crustacean host populations. Morphological and ecological variation makes them an attractive system for evolutionary studies of ... -
A New Ocean State After Nuclear War
(Journal article; Peer reviewed, 2022)Nuclear war would produce dire global consequences for humans and our environment. We simulated climate impacts of US-Russia and India-Pakistan nuclear wars in an Earth System Model, here, we report on the ocean impacts. ... -
A New Species of Osedax (Siboglinidae: Annelida) From Colonization Experiments in the Arctic Deep Sea
(Journal article; Peer reviewed, 2020)Large parcels of organic matter in the deep sea, such as whale carcasses, harbor a very specialized fauna, most famously the bone-eating worms in the genus Osedax (Annelida, Siboglinidae). Although Osedax was first described ... -
A new way forward for ocean-climate policy as reflected in the UNFCCC Ocean and Climate Change Dialogue submissions
(Journal article; Peer reviewed, 2022)The ocean plays a central role in climate change mitigation and adaptation. However, climate and ocean policies have been historically siloed. After decades of slow convergence, the Ocean and Climate Change Dialogue, decided ... -
New wine in old bottles: Modification of the Na+/K+-ATPase enzyme activity assay and its application in salmonid aquaculture
(Journal article; Peer reviewed, 2023)The Na+, K+ ATPase (NKA) enzyme is important to generate the transmembrane ion gradient in the gills, intestine, and kidneys, hence, is vital for secondary transport of fluids and different solutes in teleosts. Gill NKA ... -
Next-generation field courses: Integrating Open Science and online learning
(Journal article; Peer reviewed, 2021)As Open Science practices become more commonplace, there is a need for the next generation of scientists to be well versed in these aspects of scientific research. Yet, many training opportunities for early career researchers ... -
Nicomache (Loxochona) lokii sp. nov. (Annelida: Polychaeta: Maldanidae) from the Loki’s Castle vent field: an important structure builder in an Arctic vent system
(Peer reviewed; Journal article, 2011-07-15)The discovery of the Loki’s Castle vent field at 2,350 m depth on the Arctic mid-ocean ridge in 2008 represents the first known black smoker vent system in the Arctic region. Preliminary results on the benthic invertebrates ... -
Nitrifier abundance and diversity peak at deep redox transition zones
(Peer reviewed; Journal article, 2019-06-14)More than half of the global ocean floor is draped by nutrient-starved sediments characterized by deep oxygen penetration and a prevalence of oxidized nitrogen. Despite low energy availability, this habitat hosts a vast ... -
